In your edit in Game Center, you removed that last additional point about copying the car's folder into different versions of the game. Doesn't this apply to this car as well? Unless... since the CNET distribution is a lost demo the information was removed? Togehope (talk) 17:12, June 19, 2017 (UTC)

Acclaim, IGN and Gamespot are the 4th type of demo, right? Cars from this type of demo are 100% compatible with the retail version, since they have individual parameters files instead of an unique carinfo.txt for all the cars. That is, if you copy Acclaim, IGN-PC or Gamespot cars and paste them into your Re-Volt cars directory they will work perfectly with no modifications needed.
I removed Game Center's because nobody have (or shared) this demo yet, so we cannot say its demo type right now. In other words, we don't know if simply copy-paste its folder to the retail version will make it work. AllanO1 (talk) 15:13, June 20, 2017 (UTC)
